Year

This weekend at the Dayton Hamvention, three VK amateurs will be making presentations at the many Forums that are held on conjunction with this event. At the Young Ladies' Radio League Forum, Tina Clogg, VK5TMC, will provide a run down on the arrangements for the YL International Meet 2012 that will take place in Adelaide.

At the TAPR Forum, Phil Harman, VK6APH, will talk about Griffin - a Whisper and a Chirp. Griffin is a new HPSDR project that will provide a low power beacon exciter, covering HF, 6m and 2m, that will generate simultaneous beacons on multiple bands, each modulated independently. This revolutionary new beacon mode will enable real time propagation measurement and reporting for all HF and VHF bands.

Also presenting at TAPR is David Rowe, VK5DGR on - CODEC 2 Explained. CODEC 2 is an open source CODEC designed for low bit rate speech over HF/VHF digital radio. Whereas most low bit rate CODECs are proprietary and require licensing fees, CODEC 2 is unique in that it is open source, allowing experimentation and modification. Author and developer David Rowe will explain CODEC 2 and how it works, breaking down the complex DSP into simple terms. He will talk about the development process and the challenges he has faced along the way and present examples of CODEC 2 use with amateur radio.

For those of us who cannot attend Dayton this year, Tom K5KUB will again have his continuous live video streaming from the Flee Market and tours of the main hall. Click the following Link to http://wa5kub.com/
